' TwisrING DE ICE,

Application filed March-23, 1928.- Serial No, 264,080.

My invention relates to improvements in twisting devices, and itconsists in the combinations, constructions, and arrangements hereindescribed and claimed.

An object of my invention is to provide a twisting device in whichimprovements over my Patent No. 1,605,958, issued November 9, 1926, areembodied.

A "further objectis to provide a twisting device in which the bodyportion comprises two sections hingedly secured together, and in whichtho'handles are secured to one 01 said sections, thereby providing adevice.

which is convenient to handle and relativel durable in construction.

A further object is to provide a device'of the type employing atwo-piece die in which means is provided forautomatically opening thedevice, whereby the sections of said die will be separated.

Other objects and advantages will'appear in the following Specification,and the novel features of the invention will be particularly pointed outin the appended claim.

My invention. is illustrated in the acconr' pany drawings, forming partof this applicaticn, in which Figure 1 is a side elevation ofmy'device,Figure 2 is a sectional view taken substantially along the line 2-2--otFigure 1, and

Figure 3 is a view showing a pair of the devices mounted upon a. tubepreparatory to twisting the latter.

In carrying out my invention, I make use of a body portion 1 havingsockets 2 therein. A movable body portion 3. is hingedly secured at 4;to the portion 1. A spring 5 is provided for automatically moving theportion 3' into the dotted line position when a locking device 6 ismoved fromthe full line position into the dotted line position.

The body portions 1 and 3 are provided with a transverse substantiallyrectangular opening, for the purpose of receiving a die comprising apair of sections 8'.

tions 8-are slightly thinner than the portions 1 and 3 so that the diesections may be sup-' ported within a groove 9 provided in the portions1 and 3, see Figure 2. I

The sections 8 areprovided with intersecting openings 10 within which atube 11 may be disposed. The sections 8 are removably twisting The diesecppo ted within g ooves 9 by means of spring-pressed ball members 12.Handles 13 are disposed within the-sockets 2.

. Fromthe foregoing description of the varisrorr cs;

ous parts of the device, the operation thereof maybe readily understood.In Figure 3,1 have shown a pair of the twisting devices applied to thetube 11. o In operation when it is d'esiredto twist a tube, forinstance, the device may be secured to the latter by moving thelockingdevi'ce 6 into the dotted line position, whereupon the spring 5will automatically move the hinged portion 3 into the dotted lineposition. Atthis time, the sec-Q tions 8 are separated, since one ofthese sections moves with the portion 8 and the other is removablyretained by the portion 1.

The device is now secured to the tube 11 by moving theportion 3 intocontact with the portion 1 and securing the portions together by meansof the locking device 6. Whenit is desired to removethe die sections 8,the de vice is opened up, whereupon the sections 8 may be removed by thehand by reason'of the spring-pressed ball members 12. I-c'laim: I Atwisting device comprising a body portion, a movable' body, portionhingedly secured to said body portion, a locking device for loclcing themovable body portion with respect to said body portion, said lockingdevice being arranged to entirely disengage the movable body portion forreleasing the'latter, spring means .lor n'ioving said movable bodyportion away fron'r said body portion when said locking device isreleased, said body portion and the inovablebody portion-being providedwith transverseopenings arranged to define a single o ieningwhen-themovable body portion is locked to said bodyportion, a

two-piece die, one of said die portions being slidablydisposed-withinthe opening in said movablebody portion and the other ofsaid die portions beingslidably disposed in the opening of said bodyportion, and yielding
